5. Working Principle

After being supplied with 24V DC power, the panel automatically carries out hardware self-test, screen initialisation, keypad detection and Profibus‑DP communication handshake. It sequentially verifies power supply status, fieldbus communication, display driver and keypad modules. Once self-test completes without faults, it connects to the main control system, loads graphical configurations and process parameters, and enters normal human-machine interaction mode.

During normal operation, the panel maintains continuous high-speed data exchange with upper-level main controllers and I/O modules via Profibus‑DP. It collects field process parameters, equipment operating status, loop control data and fault alarm information in real time. After data parsing and screen rendering, information is visually presented on the display through dynamic process diagrams, numerical values, status indicators and pop-up alarms for operators to monitor system conditions.

When operators perform local operations, the panel captures keypad commands, completes logical verification and message encapsulation, then transmits commands to the main control system via fieldbus. The controller executes parameter modification, equipment start/stop, mode switching and other operations, and returns execution results to the panel for synchronous display update, forming closed-loop human-machine interaction.

The unit runs continuous real-time self-diagnosis. In case of power supply abnormality, bus disconnection, display failure or keypad malfunction, local fault prompts are activated immediately, and fault information is uploaded to the main controller. This ensures timely detection and handling of anomalies, delivering stable operation, precise data synchronisation and responsive operation.
